 * \brief 交易适配器增强综合测试文件
 * 
 * \details 本文件包含对TraderAdapter类的全面增强测试，涵盖：
 *          - 交易适配器初始化和配置管理
 *          - 订单管理（下单、撤单、查询、状态跟踪）
 *          - 持仓管理（持仓查询、持仓计算、持仓同步）
 *          - 资金管理（资金查询、保证金计算、风险控制）
 *          - 交易回报处理（成交回报、委托回报、错误回报）
 *          - 连接管理（连接状态、重连机制、心跳检测）
 *          - 风险控制（限价检查、数量检查、频率控制）
 *          - 性能测试（延迟测试、吞吐量测试、并发测试）
 *          - 异常处理（网络异常、API异常、数据异常）
 *          - 数据一致性（订单状态、持仓状态、资金状态）
